Faulted rock passed by grouting on Copenhagen sewer tunnel
Unexpected faulted rock on tunnel line 90 ft below sea level, forced grouting, and finally required bringing tunnel to surface over faulted area; poisonous hydrogen sulphide gas problem was solved by dilution with five times normal amount of air delivered to heading.
